Proceed with Nominal Sequence Plan

Operational Constraints (For next sequence)

1. Set modem heating to 10 minutes
2. Set modem reheating to 5 minutes
3. Heat modem for 5 minutes prior to transmission of large messages (e.g., images) IF messages being transmitted prior to 14:00 LST.
4. Do NOT drive/position rover behind "YOGI" (i.e., stay on the side of YOGI facing the lander). There is an LMRE antennae NULL in the vicinity of YOGI.
5. Perform Level 2 Health Checks every hour during the night to acquire night-time thermal profile.
6. Add command to set risk level back to 1
7. Shutdown operations at 15:00 LST.

Operational Constraints (General)

1. Read persistent state table at approximately 14:00 LST every Sol so that we get most recent state just prior to the end of the afternoon downlink.
2. Disable Auto Shutdown during nominal portion of each sequence

*All data downlink on Sol INCLUDING retransmitted data.

NAVIGATION PERFORMANCE:

C&N subsystem components essentially all performing as expected:

• Laser #2 is good (overcurrent seen yesterday was due to turning on 2 lasers at a time). Laser #0 and #2 both were imaged and they are in good condition. Cmd #5081: Set risk level back to 1 was SKIPPED, resulting in the risk level remained at level 2.
• Cmd #5082: Move 250mm was SKIPPED.
• Cmd #5083: Move 0 mm was SKIPPED.
• Cmd #5087: Turn right by 5 degs worked ok after the clear error (cmd#5084)
• A subsequence health check level 2 showed Y accel = -.250 g, which equivalent to a roll of 41 degs
• After this eroneous reading, Y accel readings returned to normal.
• All the subsequence navigation commands were executed without any errors.
• Cmd #5139: Read memory was not executed and the Abort sequence took place instead.
• Cmd #5111: turn toward (0, 0): showed the Z accel got one erroneous reading with the magnitude as same as the Y accel as we experienced above. This data point showed in the GeneralVI but need to be confirmed in the raw telemetry.

  Constraints:

  • Remember to set risk level back to 1.
  • The vehicle didn't perform the crabbing.

THERMAL PERFORMANCE:

Thermal subsystem components all performing as nominally

• Internal temps slightly higher than expected due to higher than expected ambient temperatures. Power Board slightly above flight allowable (41C). Will review again with Sol5-6 Night-time thermal data.
• No constraints to impose upon sequence planning

COMMUNICATIONS PERFORMANCE:

The Rover Telecom Subsystem performed nominally during the operations for SOL5. The Rover radio modem and LMRE radio modem can be used without restriction for upcoming sequences.

Statistics

• During the two downlink sessions from 9:30pm to 1:45 am,a total of 6642 frames were received from the rover by the LMRE. An additional 1570 garbled frames were also received, yielding an overall link quality of 81%.
• Rover temperature cycled from +27 to -14 deg in 14 hours after 16:43 pm MLST, then rose to +37 deg 7 hours after waking up
• Link performance is down 10 % from yesterday, but shows a similar pattern of breaking through a temperature ceiling of about 33 degrees, after which link quality becomes near perfect.
• Recommendations include repeating the same heating cycle as before, and sending as much data as possible (the higher the modem use, the better it works). Reliability peaks towards early afternoon.
• Although not as relevant, Rover side estimates of link quality are at 84 %, with a total of 25000 frames received by the lander.

Crossover Meeting:

• plan on different night ops for sol 6 (sol 5 evening will mimic last nights) with less wakeups.
• 10min/5min re heating is in place for the morning

MOBILITY PERFORMANCE:

Mobility subsystem components all performing as expected.

• No constraints to impose upon sequence planning

POWER PERFORMANCE:

Power subsystem components all performing as expected.

• No constraints to impose upon sequence planning

• Roll calculated at 362 degrees during Z accel event

Today the Sojourner Rover completed its mission success goals by taking a picture of the Lander.
